XSD came into being after "Namespaces in XML"  and is designed around documents that conform to it. In XML documents that conform to Namespaces in XML, all tokens that match the Name production in XML 1.0 must also match the NCName production. In effect, this limits IDs to being NCNames rather than Names. Cheers, Jeni  http://www.w3.org/TR/REC-xml-names/ --- Jeni Tennison http://www.jenitennison.com/
